Benefits of technology
The invention is a composition that can be used to improve the water absorbency, soil release, and anti-static properties of polyester textiles. It contains a mixture of a polyester soil release polymer and a quaternary ammonium softener. This composition can restore or enhance the natural water absorbency of polyester textiles, which was previously thought to be limited. Additionally, it can provide good levels of soil release and anti-static properties.
Problems solved by technology
It is also known that static charges may accumulate on polyesters textile fabrics, resulting in clinging and crackling.
Indeed, the repetitive use of fabric softeners during the laundering process may leave residue of softener on the fabrics, which may create a barrier to airflow and water vapor transmission of the coated fabric, leading to decrease the water absorbency of said polyester textiles, via a waterproof effect.
Because of the particular properties they hold, moisture management clothing requires some special care and it's always important, though it's a constraint and an inconvenience for end user, to check the care label, that gives specific instructions on washing and drying for such a clothing and mainly expressing to “do not use softener”.

Embodiment Construction
[0017]Polyester textiles are fabric textiles made of at least polyester yarns, thread and / or fibers. A textile or cloth is a flexible woven or non-woven material consisting of a network of natural or artificial fibres often referred to as thread or yarn. Textiles are usually formed by weaving, knitting, crocheting, knotting, or pressing fibres together (felt). Polyester fibres is used in all types of clothing, either alone or blended with other fibres, such as cotton.
[0018]Yarns, thread and / or fibers may have usual circular cross-sections or non-circular cross-section, such as for example multilobal (trilobal, pentalobal), hexagonal or irregular shapes. Yarns, thread and / or fibers may have a hollow shapes, for example produced with plug-in-orifice spinnerets, tube-in-orifice spinnerets or segment-arc spinnerets. In a specific embodiment, polyester textiles comprise yarns, thread and / or fibers having a non-circular cross-section.

Abstract
The present invention concerns then a method to recover or increase the water absorbency of a polyester textile, wherein a composition comprising at least a polyester soil release polymer and a quaternary ammonium softener is used to wash and / or rinse said polyester textile. This composition of the invention may be perfectly used during the water cycle(s) of the laundry or in the rinse cycle(s), notably used in the final rinse. The invention concerns as well a softener composition, notably used in the rinsing cycles of the laundry, comprising a polyester soil release polymer and a quaternary ammonium softener.
